ALINING DEVICE FOR SECTIONAL. BOOKCASES.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed October 2'7, 1906. Serial No. 840,798.

T0 on whom it may concern:

Be it known that I, CARL JOIIAN LUND- STROM, a subject of the King of Sweden, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Alining Devices for Sectional Bookcases, of which the following is a specification.

This invention relates to alinement stops for sectional bookcases.

In Patent No. 762,328, granted to me on June 14, 1904, I have illustrated and claimed a horizontal looking or alining device for sectional bookcases, that is, a device carried near the ends of each section adapted to be moved to project beyond the section. and engage an abutting section of another tier. The device shown in this patent could be operated only from the rear which, in most instances, is inconvenient.

An object of the present invention is to provide an alining device that may be operated from the front of the sections thus overcoming the objection to the construction shown in my former patent.

Other and further objects will hereinafter appear and will be pointed out more particularly in the appended claims.

In the drawings :-Figure 1 is a front ele vation of two end abutting sections employing an embodiment of my invention. Fig. 2 is a rear view of portions of two abutting sections provided with my alining devices. Fig. 3 is a horizontal section of a portion of one of the bookcase sections, the alining device being shown in elevation.

Referring now more particularly to the accompanying drawings, the reference characters A and B indicate two end abutting sections, each of which is provided with two alining devices, one at each end, the alin ing devices on each section being in different horizontal planes so that the devices will not interfere with similar devices on abutting sections.

To secure the alining devices to the sections, the rear wall 1 of each section is pro vided at each end with a slot 2 that opens at the edge of the rear wall and this open end of the slot is closed by a side wall The alining device is fitted in the slot before the rear and end walls are secured together and is thus held in this slot which forms a track or guide for the device' My improved alining device comprises a finger piece 4- located within the section so as to be engaged from the front thereof; a reduced neck 5 which slides in the slot 2; and an alining portion 6 which is adapted to project beyond the end of the corresponding section when the neck is in its position nearest the adjacent end wall. This alining portion 6 is provided with a rearward extension 6 which serves to maintain the slot closed when the device is in operative position. Thus the alining portion 6 is of such length as to maintain the slot closed when the device is in either of its positions, and it is therefore apparent that the device also prevents the entrance of dust through the slot to the .interior of the section.

What is claimed is 1. The combination with a bookcase sec tion; of alining devices movably connected to the rear wallof the section, said devices being adapted to be projected beyond the ends of the section and having means operable from the interior of the section to project them.

2. The combination with bookcase sections of an alining device slidably connected to the rear of each section, each alining device having a portion projecting through the back of the corresponding section whereby it may be operated from within the section.

3. The combination with a bookcase section having a slot in its rear wall; of a slidable alining device having a portion projecting through said slot, said projecting portion i11- cluding an enlarged free end forming a finger piece within the section, the alining portion of the device being arranged upon the outside of the section and adapted to maintain the slot closed at either limit of its sliding movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
